Camera view goes crazy to another view
The problem was that you set the Plane as a local camera here. So every time you pressed 0 key it, blender showed you the local camera set as the plane and thus you were seeing the inside of the washing machine.

Just deselect the "Use Local Camera" checkbox, that would allow you to change the Local Camera. Select the camera of you scene using the eye dropper tool or by the list.


and now when you press the 0 key, it will show what you camera is looking at.
